3 'Claims. 1

My present invention relates to improvements in faucets of the constant temperature type utilizing a combined reciprocable and rotary valveor screw actuated plug, and an oscillatible valve device, for controlling the volume and the temperature of the water passing through and dispensed by the faucet.

By the combination and compact arrangement of the volume control plug-valve, with a pivoted vane temperature control or mixing valve, in a single casing, these valves are readily accessible for operation to provide a cold water supply, a

hot water supply, and a mixture of hot and cold water in varying degrees of temperature as well as in a constant flow; and the desired supply may be selected and manually controlled asit is-dispensed from the faucet.

While the faucet of my invention is adapted for use with various fluids or liquids, it is especially applicable for domestic uses with sinks, wash-bowls, bath tubs, shower baths, and other plumbing fixtures, where this type of faucet is desirable.

The primary object of the invention is the pro- .vision of a faucet of this type that is simple in construction and operation, and which may be manipulated in such manner as to dispense the selected and desired volume and temperature of water without waste, but with efficiency and economy.

In carrying out my invention I utilize a casing having a plurality of water inlets and a valve device for selected control of these inlets, a single outlet and its volume-control valve, and an intermediate mixing chamber, together with controlled communication between the inlets, the outlet and the mixing chamber. 1

The. invention consists in certain novel combinations and arrangements of parts involving these designated features as will be more specifically set forth and claimed.

In the accompanying drawings I have illustrated one complete example of the physicalembodiment of my invention wherein the parts are combined and arranged in accord with a satisfactory mode that has been devised for the practical application of the principles of the inven tion, but it will be understood that changes and alterations may be made in these exemplifying and mechanical structures. Such changes and alterations are indicated in a modified disclosure of the invention in the accompanying drawings, which changes and alterations also come within the scope of my appended Figure 1 is a vertical longitudinal sectional view of a faucet embodying my invention, as at line B-B of Fig. 2. V

Figure 2 is a horizontal longitudinal sectional View of the faucet as at line A-A of Fig. 1.

Figure 3 is a top plan view of the handle, detached, for operating the oscillatable mixing valve device.

Figure 4 is an end view as seen from the left in Fig. 1 showing the plurality of inlets to the faucet.

Figure 5 is a vertical longitudinal sectional view of a modified form of faucet embodying the invention, as at line 5-5 of Fig. 6.

Figure 6 is a horizontal longitudinal sectional view of the faucet ofFig. 5, as at line E6.

Figure '7 is an end view as seen from the left in Fig. 5 showing the hot and cold water inlets to the valve casing.

In both forms of the invention disclosed in the drawings the casing which encloses the operating parts is provided with a rear extension forming a cold Water chamber 1 and a hot Water inlet chamber 2, divided and separated by an interior vertical wall of partition 3, and this rear extension is fashioned with threaded nipples ll and 5 for the attachment of cold and hot water supply pipes respectively.

These inlet chambers communicate through inlet ports 6 and l with a circular mixing chamber that is formed within the body 8 of the casing by an integral arcuate wall or partition 3, and the bottom of the circular mixing chamber is closed by means of a threaded circular plate 5 that forms part of the bottom wall of the casing. The integraloutlet nozzle H] of the faucet is alined with the center of the mixing chamber and the partition 3 separating the inlet chambers, and it is located above the horizontal plane of the mixing chamber and in communication therewith through a horizontal annular seat or port H opening into the chamber.

. supply and permit flow of cold Water to the outlet port.

In Fig. 6 the gate is shown in full lines to permit mixing, of the'hgt and coldwater..suphlies, and

in dotted lines the gate is in position to cut 015! the cold water supply and permit free flow of the hot water supply to the outlet valve II.

The gate valve or regulating vane is designated as a whole by the number I2 and it is provided with a central swivel pin I3 having its protruding ends journaled in sockets bored or drilled in the inner upper face of the plate 9 and the flat face of the wall over the mixing chamber.

One end of the swiveled gate is fashioned with a forked bearing I5 with which an operating pin I6 co-acts to swing the gate to the three adjustments with relation to the outlet port H above described.

In Figs. 1 and 2 the operating pin I6 is rigidly mounted in and projects downwardly from the tapered head-section I4 of a combined reciprocable and rotatable plug valve for the outlet port II, which valve as a whole or unit is supported in a cylindrical head I! rising vertically from the upper part of the body 8 of the casing.

.The stem I8 of the head section I4 passes upwardly through a non-rotary, but vertically reciprocable section I9 of the valve, and an operating handle I9 having a. perforated head or disk is fastened, as by screw upon the upper reduced and protruding end of the valve stem. From this description it will be apparent that by turning the handle I9, which has a bearing on the upper fiat face of the valve section I9, the stem I8, valve head I4, and pin I6 may be turned to adjust the oscillatable or swiveled gate valve or regulating vane I2 for controlling the fiow of water through the mixing chamber.

The sectional valve I l-49 as a unit is reciprocable for opening and closing the outlet port I I that is located intermediate the mixing chamber and the outlet nozzle of the faucet; the valve head I4 is both rotatable and reciprocable, while the valve-section I9 is non-rotary but reciprocable.

The outlet valve for-controlling the volume of water passing through the port I I is mounted in a bushing 2| which is externally threaded and secured in the internally threaded casing head I7, and the bushing is provided with a guide pin 22 projecting radially toward the axis of the plug valve into a guide groove 23 in the exterior surface of the reciprocable section I9 of the plug valve.

A clamp nut M, which is internally threaded, is screwed down on the exteriorly threaded part of the bushing 2i, and this nut is flanged to retain a flanged internally threaded sleeve 25 which meshes with the external threads on the upper end of the plug-section I9.

A valve control handle 26, having-an open-head or ring 21 and an attaching lug 2 8, is mounted on the clamp nut 24, with the lug engaged in a slot or groove cut through the exterior threads of the sleeve 25, as indicated in Fig. 3.

By turning the handle 26, together with the internally threaded sleeve 25, the threaded section I9 of the plug valve may be reciprocated, and as the head section I4 of the plug moves with section I9, the port Il may be opened and closed to control flow of water through the port It.

In the form of the invention disclosed in Figs. 5 and 6 the position of the gate valve or regulating vane is reversed from that of Figs. 1 and 2, and the swiveled gate is adjusted by means separate from and independent of the means for controlling the outlet valve.

In Figs. 5 and 6 the operating pm It is mounted-v on a circular head or disk 30 which is rigid with a stem 3| that is journaled in a bore of a cylindrical head 32 of the casing body, and a handle 33 is mounted on the upper protruding end of the stem for use in swinging the pin to regulate and control the gate or vane I2.

In Fig. 5 the outlet port I I between the mixing chamber and the dispensing nozzle is controlled and regulated by means of a rotary and reciprocable valve 34, the screw stem or threaded stem 35 being provided with a rigidly fixed handle 35, for lifting and for depressing the valve 34 with relation to its seat or port II.

A bonnet 3! is threaded on the externally threaded integral bushing 38 of the casing to co-act with the threaded valve stem and to retain the valve unit in working condition.

While I have shown the faucet in horizontal position for attachment to the hot and cold water supply pipes, it will be understood that the device as a whole may be installed in vertical position; and while the water inlet chambers are shown alined with the longitudinal axis of the device, these chambers, with their nipples, may be located laterally of the longitudinal axis of the valve casing in adapting the device to a variety of installations.

In both forms of the invention shown in the drawings the gate valve is adapted for adjustment to divide the mixing chamber into two conduits, one leading directly from the cold water inlet port to the outlet port. and the other leading from the hot water inlet port to the outlet port,and the flow of hot and cold water may be regulated to vary the temperature of the mixture admitted to the outlet port I i.

In Figs. 2 and 6, in full lines, the swiveled gate divides the mixing chamber, evenly, into two conduits supplying an equal volume of hot and cold water to the divided bottom opening of the outlet port Ii. The degree of temperature may be regulated by moving the gate valve across the lower opening of the port to partially reduce the area of the port at the cold water side of the gate, and increase the area of the port at the hot water side; or the temperature may be regulated by moving the gate across the lower opening of the port to partially increase the area of the port at the cold water side and decrease the area of the port at the hot water side.

For a cold water supply to the port II, as indicated by dotted lines in Fig. 2, the gate is swiveled entirely across the bottom opening of the port to close the hot water supply and completely open the cold water conduit between port 6 and port II. For a hot water supply to the port I I, as indicated by dotted lines in Fig. 6, the gate is swiveled across the bottom opening of the port II to close the cold Water supply, and to open the conduit between ports I and i I.

Having thus fully described my invention; what I claim as new and desire to secure by Letters Patent is:
